摘　　要：为了实现在役油气管道周边爆破作业风险的定量计算,需通过对在役油气管道周边存在的爆破作业活动产生的振动、冲击波,以及其他可能给管道和运营人员带来危害的风险进行分析。应用爆破振动和冲击波超压计算,结合相关标准要求,确定爆破振动和冲击波超压的安全允许距离。同时,在确定爆破振动安全合理判据时,应注意管道承受的来自爆破振动力的大小和状态除受爆破条件影响外,还受地质条件、管材特性、管道敷设方式以及振动传播路径等因素的影响。基于这些综合因素,提出相应的控制措施,为管道运营企业决策如何应对管道周边爆破作业活动时提供依据。In order to achieve quantitative calculation of risks from blasting operations around in-service oil and gas pipelines,an analysis is made of risks of vibrations,shock waves and other possible hazards to pipelines and operators caused by blasting operations around in-service oil and gas pipelines.Permissible safe distance of blast vibration and shock wave overpressure is determined in accordance with calculations of blast vibration and shock wave overpressure as well as relevant standard requirements.In addition,criteria for safe and reasonable blast vibration is determined in accordance with size of blast vibration force on pipelines,blasting conditions,geological conditions,pipe characteristics,pipeline laying methods,propagation path and other factors.Based on these comprehensive factors,corresponding control measures are proposed to provide a basis to the pipeline operating enterprises to make a decision about blasting operations around pipelines.
